Dynamic Phase Matching Control for Enhanced Four-Wave Mixing Processing of Polarization-Division-Multiplexed Coherent Optical Signals

Abstract

By applying gain-transparent stimulated Brillouin scattering to a dual-orthogonal-pump four-wave mixing scheme, we introduce additional optical phase shift along a nonlinear fiber to improve the efficiency on polarization-insensitive processing of PDM-QPSK communication signals.

Optical Phase Quantizer Based on Phase Sensitive Four Wave Mixing at Low Nonlinear Phase Shifts

Francesca R. Parmigiani, Graham Hesketh, Radan Slavı́k +3 more

We propose and demonstrate a new phase-sensitive (PS) scheme based on four-wave mixing followed by a polarizer to achieve an ideal binary step-like phase transfer function at nonlinear phase shifts as low as 0.3 rad by significantly increasing the parametric deamplification component. PS operation is obtained by polarization mixing the phase-locked and orthogonally polarized signal and idler, which is generated in a degenerate dual-pump vector parametric amplifier.

Intra-cavity frequency shifted laser pumps for non-degenerate and partially coherent Bragg-Scattering FWM in nonlinear fiber

Katarzyna Krupa, Michela Bettenzana, Alessandro Tonello +6 more

Nonlinear effects in fibers with partially coherent pumps have attracted a great interest in view of their potential for polarization insensitive wavelength conversion and the increased resilience to Stimulated Brillouin Scattering [1]. In this work we experimentally study the problem of non-degenerate four-wave-mixing (FWM) by using a pair of partially coherent pumps, and focus our attention on a specific type of FWM, which is generally called “Bragg-Scattering” (BS-FWM). This kind of FWM has attracted a renewed interest because of its intrinsically low-noise nature which makes it potentially applicable for light-by-light manipulation even for very faint signals such as quantum keys [2].

Polarization-Assisted Phase-Sensitive Processor

Francesca R. Parmigiani, Graham Hesketh, Radan Slavı́k +3 more

We propose and experimentally demonstrate a phase-sensitive optical processor, capable of generating two codirectional and π-phase-shifted phase-sensitive amplifiers (PSAs) in a single device. Phase-sensitive operation is obtained by polarization mixing a phase-locked signal/idler pair generated in a degenerate dual-pump vector parametric amplifier based on four-wave mixing in a highly nonlinear fiber. We refer to this configuration as a polarization assisted PSA and demonstrate some of the applications that it may find. First, we experimentally demonstrate the regeneration of a binary phase shift keying signal in a system that requires only a very low nonlinear phase shift of 0.35 rad. Second, we decompose a quadrature phase shift keying (QPSK) signal into its in-phase and quadrature components. While application to a QPSK signal is shown in our demonstration, we demonstrate numerically that any complex modulation format signal can be decomposed using this approach. Finally, we use our processor to regenerate QPSK signals in a single nonlinear device.

Nonlinear Optical Signal Processing and Generation of Quantum States using Intermodal Four-wave Mixing

Karsten K. Rottwitt, Mario A. Usuga Castaneda, Erik Nicolai Christensen +2 more

The strong interest in space-division multiplexing of classical communication signals has resulted in development of optical fibers that support propagation of multiple modes. This has paved the way for progress in signal processing using multiple modes and four-wave mixing between these. More specifically, careful design and knowledge of optical properties of individual modes enables phase matching in four-wave mixing that is otherwise not possible with single-mode fibers. This enables signal processing using four-wave mixing between higher-order modes for e.g. frequency conversion over a wide bandwidth. In addition, processing and creation of quantum states has also been demonstrated using four-wave mixing, including generation of photon pairs. In this work we review recent progress in signal processing and generation of quantum states using four-wave mixing.

Spectral inversion with no wavelength shift based on four-wave mixing with orthogonal pump beams

Kyo Inoue

Generation of phase-conjugate light with no wavelength shift that utilizes four-wave mixing (FWM) with two orthogonal pump beams is discussed. Owing to the polarization properties of nondegenerate FWM, phase-conjugate light generated at the original signal wavelength can be obtained. An experiment using dispersion-shifted fiber as an optical nonlinear medium confirms the proposed scheme.
